Patented June 15, 1943 DISPLAY BOX c'ovna Lewis Douglas Young, Providence, R. 1., assignor to Douglas Young, Inc., a corporation of Rhode Island Application October 11, 1940, Serial No. 361,468

2 Claims. (Cl. 206-44) This invention relates to a display box, more particularly to the cover for the box.

In the use of transparent material for the cover of a box, it has been found that where a curved top is desired that the edges of the box parallel to the center line of generation of the arcuate top bulge, and this invention has for its primary object to provide an arrangement whereby this bulging of the edges of the cover will be prevented.

Another object of the invention is to provide a simple and strong construction of box cover which will provide an attractive appearance in position on the box and over the merchandise which it is to protect.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in'the appended claims.

In the accompanying drawing:

Fig. 1 is a perspective view of a box equipped with my novel transparent cover;

Fig. 2 is a perspective view of the cover alone;

Fig. 3 is a section on line 3-3 of Fig. 2;

Fig. 4 is a section on line 4-4 of Fig. 2; and

Fig. 5 is a fragmental sectional view illustrating in greater detail the securing of the end wall in position on the cover.

Transparent box covers have been made in various forms or shapes from either wholly transprovide downwardly-extending side walls i3. This crease l2 forms a distinct line of demarcation between the top II and the side It and serve to provide a corner and as an angle formation to stlfien the side 13 throughout its length so that no bulging of the middle portion of this side will occur.

The ends ll of the top and iii of the side walls .are rolledinwardly as illustrated at It for the top wall (see Fig. 5) and at H for the end walls (see Fig. 2) and serve to stiffen the same. A separate end wall II is positioned inwardly of the rolled edges l8 and H. Adhesive it along this roll is provided to securely cement the end wall I. to the top and side walls and complete the cover.

The cover is removably positioned upon the box designated generally 20, consisting of bottom 2| and upwardly-extending flanges 22 which telescope within the side and end walls l3 and II. The height of the end walls It will serve to accommodate the height of the flanges 22.

The creasing I! serves to retainthe side walls I ll snugly against the flanges 22 and causes the parent celluloid-like or acetate material or part- I E ly of such material. Frequently it is desirable that the box have a curved top, and I have heretofore provided a box with a curved top extending in an uninterrupted arc of curvature from one side edge of the box to th other with no gether and detracts from the appearance of the box. In ordervto overcome this bulging I have tried various inward curving processes but without success. .I have found, however, that by creasing the transparent acetate or other material that this bulging no longer occurred; and the following is a more detailed description of the present embodiment of this invention, illustrating the preferred means by which these advantageous results may be accomplished:

With reference to the drawing, particularly Fig. 4, 10 designates a sheet of transparent socalled acetate material curved to provide an areuate top wall It and a sharp crease at I! to cover to present a very attractive appearance and more effectively prevent the entry of dirt or other foreign matter from the materials contained within the box.

I claim:

1. A display box comprising a body having upstanding side and end walls and a transparent cover comprising top, side, and end walls, said top and side walls being formed from a single piece of material extending from the free edge of one side wall to the free edge of the other side wall. said top wall being curved about an axis lengthwise of said free edges and the junction between said top and side walls being formed by a fold to provide a sharp corner, theupstanding walls of said display box being positioned within the walls of said cover.

2. A display box comprising a body having upstanding side and end walls and a transparent cover comprising top, side, and end walls, said top and side walls being formed from a single piece of material extending from the free edge of one side wall to the free edge of the other side wall, said top wall being curved about an axis lengthwise of said free edges and the Junetion between said top and side walls being formed by a fold to provide a sharp corner, and end walls to conform to the cross section of the top and side walls secured to the said edges, the upstanding walls of said display box being positioned within the walls of said cover.
